In our case there was no discount to be had from the AP, but the dealer was good to us. He put the floormats in, almost half a tank of fuel, and as I look after our motors, the dealer very generously gave us a complimentary Diamondbrite car care kit.
I asked for the Subaru tailored low cargo mat, and the Subaru front and rear shaped mudflaps. They supplied and fitted all of those for £160. Very happy with that 👌
